The gravitational force between two objects is given by
![F=G \frac{m_1 m_2 }{r^2}](https://tex.z-dn.net/?f=F%3DG%20%5Cfrac%7Bm_1%20m_2%20%7D%7Br%5E2%7D%20)
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the separation between the two objects
In this problem,
![m_1 = 175 kg](https://tex.z-dn.net/?f=m_1%20%3D%20175%20kg)
,
![m_2 =15 kg](https://tex.z-dn.net/?f=m_2%20%3D15%20kg)
and
![r=2 m](https://tex.z-dn.net/?f=r%3D2%20m)
, therefore the gravitational force between the two objects is
Answer:
No
Explanation:
She will not be able to measure the length of her window accurately due to instrumental error from her choice of instrument. The elastic nature of her tape would alter the measurement because it will stretch as she is taking her readings, thus reducing the true measurement of the length of her window.
To measure the length of her window, she could use an inelastic tape rule or a metre rule. These instruments would eliminate instrumental error.
Answer:
For example, an earthquake of magnitude 5.5 releases about 32 times as much energy as an earthquake measuring 4.5. Another way to look at this is that it takes about 900 magnitude 4.5 earthquakes to equal the energy released in a single 6.5 earthquake.
